    摘要: There is provided a loop fastening material for engaging a suitable male mechanical fastening element for a backing substrate of an oriented sheet material having a first face and a second face and substantially continuously attached to at least the first face a plurality of discrete, multi-filament transversely expanded yarns, such yarn filaments providing open loop structures. The yarns are expanded by transverse orientation of the backing to which it has been previously attached by extrusion bonding, adhesive bonding or the like. The resulting loop fastener provides a low cost, readily manufactured loop having good fastening properties to hook materials.

    摘要: A nonpolarizing beamsplitter is provided, which includes a multilayered stack of alternating layers of a first material and a second material. The first material layers are uniaxially birefringent, and the second material layers are optionally uniaxially birefringent or isotropic. The layers have index of refraction relationships such that for an incident beam having a useful bandwidth, a p-polarized component and an s-polarized component striking the beamsplitter at any angle of incidence .theta. within a desired range, the beamsplitter exhibits substantially the same average reflectivity for the p-polarized component of the incident beam as for the s-polarized component. The invention also includes a method of making a nonpolarizing beamsplitter.

    摘要: A hollow, cylindrical light conduit for transporting light generally longitudinally therethrough and distributing light therealong includes a cylindrical wall member of a transparent material. The wall member has an inner cylindrical smooth surface and an outer cylindrical structured surface having an array of isosceles prisms arranged side by side thereon. The faces of adjacent prisms extend longitudinally along the cylindrical wall member and are aligned at the same desired prism angle relative to one another. The light transporting performance of the light conduit, achieved by total internal reflection, and the light distributing performance of the light conduit, specifically relative to radially aligned, high incident angle longitudinal light rays in planes parallel or near parallel to the prisms, is optimized as a function of the desired prism angle between the faces of adjacent prisms.

    摘要: Orthodontic archwires are packaged between pairs of flexible sheets that are releasably fixed to each other. The archwires are spaced apart from each other between the sheets and arranged in a nested array wherein a portion of one archwire is received within the U-shaped configuration of another archwire. Lines of weakness extend between adjacent pairs of the archwires for enabling detachment of one archwire from remaining archwires of the assembly when desired.

    摘要: A method of preparing preferred abrasive grain includes: preparing a dispersion including alpha alumina oxide monohydrate and zirconia sol therein; converting the dispersion to base grit material; and sintering the base grit to form abrasive grains. The presence of the zirconia sol within the dispersion from which the base grits are formed provides an improved abrasive grain. The improved abrasive grain are useful in abrasive products.
